BACK FOR CAR-SEATS.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, GEORGE B. Ker-mien, a citizen of the United States,reslding in certain Improvements. in Backs for Car- Seats, of which thefollowing is a speeifica tion.

One object of my invention is to make a metal frame for-the back of acar seat and to couple the cushion supporting plates-to the frame sothat they will be rigidly tonnected thereto, but free to yield underpres sure,

A further object of the invention is to provide means for deta'ehablysecuring the back to the supporting arms, and 'further to make thecovering in the form of a bag closed at the top.

In the accompanying drawings Figure 1, is a sectional perspective viewof the back of a car seat illustratingmy invention;

Fig. 2, 1s a perspective view oi the lower half of the frame brokenaway;

Fig. 3, is a perspective view of the upper half of the firame brokenaway;

Fig. 4, is a perspective view of a portion of the clamping bar of theupper frame;

Fig. 5, is a perspective view oi the lower clamping bar;

Fig. 6, is a perspective'view of one of the side clamping bars;

Fig. 7, is a'dctached perspective view of the cushion supporting plate;

'Fig. 8, is a detached perspimtive view showing the two sections oi thecover conno'tted prior to being placed over the frame;

Fig. 9, is a side \"iew of the completed seat back; and

Fig. 10, is an end view. lhe main irame is made in two sections, the endoil one Frame fitting into the end of the other and these two i'ramosmay be secun-i'l together by brazing, welding, or other suitable means.The lower 'l'rame- 1 has a longitudinal memlu-r 2 and vertical endmembers 3 and is made ineross section as shown lmviug an undercutgroove4: at

ilu-Lbotlour andat each side to receive the clamping-bars o "ends of thecover 7 to the frame; the ends (itii'lll'l ylllg the undercut space inthe main i'rame. 'lho'lower clamping bar 5 is curved in cross section,Fig. fi,'and when it is adjusted in the undercut space itis flattened,

' the groove; 20.

and (3, which confine the extends the longyitiulinal rib 16 of the uppermain frame 17 and isrou nded at 18 to fit the rounded portion 1!) ofsaid frame. The rib is hollow and forms a groove 20 for the reception ofti e ends 21 of the cover? I'.atented-l\'[ar. 27, 1.917..

which, in'the present instance, is made of l'atan. The -frame is roundedat the upper edge so that the cover will have a smooth bearing upon theiramc, as clearly illustrated in Fig. 1. Tl'K cover is held to the uppermain frame by a U-shaped hollowbar23 extending down on ea h side thereofand retaining the portion 21 of the cover in The cover is made in two,pieces and the upper ends are joined to gether face-to i ice by a lineof stitching 24. It is th.is-1')ortio l of the cover which extends intothe groove 20'.

The upper in liIl frame 17 has tongues 25 at the lower ends of the sidemembers and these. tongues pass into the lower main frame '1 back i tthe' llanges 9. and can be SWZIII'tNi thereto by brazing or welding.

lhe end inel ibei's 3 oi the lower frame 1 are tapered and the groove 4also,

I tapered to I'OGtlVU the tapered side bars 6- lit these groovis and extend over the ends oi the U-shapel bars 23 of the upper-sectIon, makinga neat lit and. allowing for the, removal. oi the back section from thesupporting arms when. necessary. 'lhese supporting arms are soconneetedto the seat mechanism that the back can be sbil'twl froln oneside. to the other and the back section, being louble, need not beturned.

.The cushion supporting plates, shown in Figs. .l and 7, have a series.oi ,trans\'erse rib s 28 for the inrpose of making the plates 29, whichare attached seen that I am enabled to mak more flexible than if madeflat, and located between the two members 13 are the springs rivets, orother fastenings. Between the cushion supporting plates and the covermaterial 7 is a lining 31 of hair, or other suitable'material,preferably backed with burlap or other fabric.

From the above descriptibn it will be e a light and substantialframe'for the back of a car seat, the same being made of sheet metalbent into shape;.the cover for theseat being secured to the lowerportion of the frame by undercut plates which firmly fasten the materialto the frame, the upper portion being secured by a U-sha ed hollow barwhich is attached to the cEiameby two or -more screws, dTother sui bleif'astenings.

By making the frame in the manner shown, I am enabled to attach twopertions of the cover by a row of stitching in order toform a bag whichis placed over 'tion of the frame; bottom plates adapted to clamp thefabric the frame, the seam entering the "groove in the top frame, ashereinbefdretdescribed and being covered by the tubular bar 23.-

- By making the clamping bars 6 of sheet metal, I not only provide aretaining rib for the material, but also form an undercut socket'for thearms which support theback.

While I have described my invention particularly as. a back; for a carseat, it will be understood that the invention may be used in any placewhere a double back is desired,

or where a backis upholstered on both sides. I claim: a I I 1. Thecombination in a car seat back, of

a main frame, the upper portion of the frame having a centralgroovetherein and the lower portion of the frame having an undercut groove; afabric covering adapted to the frame; a U-shaped bar adapted to clampthe fabric covering to the upper porand-separate side. and

in the frame; e '2. The combination in a back structure, of

grooves "in the lower portion ofthe' aframe'; the upper part of saidframe havl mg a recess and having ,a central groove therein; a barfittingthe recess but not extending into the groove; and .a coveringmade in two sections secured together, the

portion of the back.

ends of'thetwosections which are secured together extending intothegro'ove in the frame, said bar retaining the covering in the grooveand forming a finish'for the upper 3. The combination in the back'of acar to. plates 30 by said frame, the ends 0 frame being .ing undercutgrooves the cover material to ionsuppo'rting plate having two sidemembers and an lntegral connecting member,

seat structure, o f 'a frame; cover material; means foratta chm theexterior of the rame; a U-shaped cushsaid connecting member being shapedto'conform to the inner'side of the upper portion oiithe frame and beinheld in position by the side members of the supporting plate being.shaped to form an interlock, the lower also shaped to receive the1nterlocking portions of the supporting plate.

4'. The combination in a car seat back, of a metallic-frame havingtapered undercut portion of the maiI 1 70.

grooves at each side near the lower end and an undercut groove at thebottom; side clamping plates having undercut ribs adapted to the taperedside grooves of the frame; a separate clamping plate adapted to thebottom groove; frame by said plates; and means for securing the uppersection of the cover to the frame. 7

5. The combination in'the back of a-car portion of the frame havingagroove therein; a Ueshaped clamping bar coverlng the groove andextending on each side of the a cover confined to the. 30

seat, of a quadrangular frame, the upper frame,-the lower portion of theframe havranged to enter said grooves;- a two-part clamping bars ar-' 5cover having a senmat the upper edge, one

part .being stitched to the other part face to face and forminganinternally extending ribwhich enters... .the groove in the upper 9portion. ofthe frame-the U-shaped bar covering the seam and the freeends of the covering extendinginto the grooves in the lower portion ofthe frame nndbeld therein by the above mentioned clam-ping bars.

6. The .combinatiomin the back of-a car seat, of a metallic frame havingtapered' at theside near the lower portion of grooves the back twosubscribing witnesses.
